There is no "potential". They have the right and duty, under the 10th Amendement of the Constitution, to nullify the illegal ruling of the Federal court. The Court has absolutely no jurisdiction over this matter, and should not even have considered it. What will the Court do to enforce their $5k per day fine anyway? Send Federal Marshalls to collect it? George W. Bush can with the stroke of a pen deny any such cooperation of the Marshalls service. Has this nation just decided to totally ignore what is written in the Constitution and simply hand over the reigns of power to the Judiciary? Utter madness.
